Dependency injection is a design pattern in which components are given their dependencies rather than creating them internally.
Dependency injection helps in making components more modular and easier to test.
It promotes loose coupling between components.
There are three types of dependency injection - constructor injection, setter injection, and interface injection.
Callback hell is a situation where multiple nested callbacks make the code difficult to read and maintain.
Occurs when multiple asynchronous operations are nested within each other
Can lead to unreadable and unmaintainable code
Can be avoided by using promises or async/await
Lazy loading is a technique used in web development to defer loading of non-essential resources until they are needed.
Lazy loading helps improve page load times by only loading resources when they are required.
It is commonly used for images, videos, and other media files on websites.
Lazy loading can be implemented using JavaScript libraries like Intersection Observer or by using native browser features like loadin...
Prop drilling is the process of passing down props through multiple levels of components in React.
Prop drilling can lead to complex and hard-to-maintain code.
It can be avoided by using Context API or Redux for state management.
Example: Passing props from a parent component to a deeply nested child component through intermediate components.
Memoization is a technique used in programming to optimize performance by storing the results of expensive function calls and returning the cached result when the same inputs occur again.
Memoization helps reduce redundant calculations by storing the results of function calls in a cache
It is commonly used in dynamic programming and recursive algorithms to improve performance
Example: Fibonacci sequence calculation c...
This question tests logical coding skills in C programming through problem-solving and algorithm design.
Understand the problem statement clearly before coding.
Break down the problem into smaller, manageable parts.
Use appropriate data structures like arrays, linked lists, etc.
Write pseudocode to outline your logic before implementing in C.
Test your code with edge cases to ensure robustness.
Quick sort is a popular sorting algorithm that uses a divide-and-conquer approach to sort elements in an array.
Quick sort picks a 'pivot' element from the array and partitions the other elements into two sub-arrays according to whether they are less than or greater than the pivot.
It then recursively sorts the sub-arrays.
The pivot selection can greatly affect the efficiency of the algorithm. Commonly used methods i...
Join in SQL is used to combine rows from two or more tables based on a related column between them.
Join is used to retrieve data from multiple tables based on a related column
Types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN
Example: SELECT * FROM table1 INNER JOIN table2 ON table1.column = table2.column
